DSE Analytics Solo datacenters do not store any database or search data, but are strictly used for analytics processing. They are used in conjunction with one or more datacenters that contain database data.

DSE Search allows you to quickly find data and provide a modern search experience for your users, helping you create features like product catalogs, document repositories, ad-hoc reporting engines, and more.

Note: When user credentials are specified
in plain text on the dse command line, like dse -u
username -p password,
the credentials are present in the logs of Spark workers when the driver is
run in cluster mode.

The Spark Master, Spark Worker, executor, and driver
logs might include sensitive information. Sensitive information includes
passwords and digest authentication tokens for Kerberos guidelines mode that are passed in
the command line or Spark configuration. DataStax recommends using only
safe communication channels like VPN and SSH to access the Spark user
interface.
